lol....yes there has been a HUGE amount of changes in the past several years especially.
I shudder to think what we were teaching back in 1999, it was rudimentary compared to today!
I had the privilege last year to be the S3, Chief of Training for the Joint Mulitnational Readiness Center in Germany
We were (are) adapting and changing on the fly as we learned lessons and were able to deal with a complex battlefield!
Back in the 1990s we would clear buildings with a frag grenade, HC Smoke, and a SAW going into the room! ...yeah....not so much these days!
When I left, I was trying to get Blauer suits intergrated with our simunitions to allow our OPFOR to do the 21 Feet Scenarios under live conditions.
Today, ordinary soldiers are doing what was in the prevue of Ranger Battalions and SF. Lots has changed!
